What do you need to do to rationalize a denominator with a cube root in it?

When a denominator has a higher root, multiplying by the radicand will not remove the root. Instead, to rationalize the denominator we multiply by a number that will yield a new term that can come out of the root. For example, with a cube root multiply by a number that will give a cubic number such as 8, 27, or 64.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
